JTable中的JCheckBox状态无法改变，也无法选中：下面是我的源代码，请热心的人帮助，自己查资料什么的弄了好久了，先谢了
public class TestSetRouterPane extends JPanel{

[解决办法]
public boolean isCellEditable(int row, int column) {
return false;
}
单元格都无法编辑，这里有问题
[解决办法]
public boolean isCellEditable(int row, int column)
{
if (column==0) {
return true;
}
return false;
}
这样修改下，试试。
[解决办法]
界面部分没有问题的，可以选中并改变状态。
[解决办法]
可以肯定的是界面部分完全没有问题，这个你可屏蔽掉业务证实，你可以尝试调试下看是不是其中的业务数据部分出现异常了？
[解决办法]
//获取鼠标点击的行的位置（及行数）
Point mousepoint =e.getPoint();
System.out.println("获取鼠标点击的行的位置（及行数"+tab.rowAtPoint(mousepoint));
testTable.getTableHeader().addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e){
Point mousepoint =e.getPoint();
if(tab.rowAtPoint(mousepoint)&&columnAtPoint(mousepoint) ==0){//如果点击的是第0行第0列checkbox这一列
JCheckBox Checkbox = (JCheckBox)check;
boolean b = !check.isSelected();
check.setSelected(b);
testTable.getTableHeader().repaint();
}
}
});
tab.getColumnModel().getColumn(4).setCellEditor(new DefaultCellEditor(new JCheckBox()));//可编辑复选框
tab.getColumnModel().getColumn(4).setCellRenderer(new TestTableCellRenderer1());
//渲染成复选框的形式;
//这两步不写,复选框就显示不了;
//重写getTableCellRandererComponent方法;你出错的地方,没有将你点击复选框的动作,获取且操作;
class TestTableCellRenderer1 extends JCheckBox implements TableCellRenderer{
@Override
public Component getTableCellRendererComponent(JTable table,Object value, boolean isSelected, boolean hasFocus, int row,int column) {
System.out.println("value -:"+value+"-");
//value是点击返回的值;
if((boolean)value){
this.setSelected(true);
}else{
this.setSelected(false);
}
return this;
}
}
